Porsche Only Track Evening: Brands Hatch. Spectators Welcome

What a great evening at a great track!

On my noise test I registered 102.7db at 5200rpm and then after some discussion I was tested again at 101.8 at 5000 so I was allowed on. This is a on a 993 with standard exhaust but with sports airbox. No problems on track.

I had an initial scare on the first few laps waiting for the 997 convertible to 'invite' me to overtake and I made a move to pass at the same time as someone behind me. Apologies to whoever that was.

Other than that it was a great evening with great driving standards and most people not hanging about. There was a nice variety of cars on track.

Thanks to Ian for taking me for a few laps in his 997. That was an eye opener...the power...the grip!

Simple and safe mod that looks like it sets fire to your PU. Those brown marks look like burns :eek:

Not the case.

Straight on shot showing the existing issue.

It's a moderate divert of the exhaust gas be enough to reduce db's by up to 2.

So what are the brown marks then? Don't get me wrong I really like the idea, but there is a nasty mark on the pu just above the exhaust pipes and at either side to a less extent. I've seen these before with aftermarket bolt ons / exhaust and they were burn marks?

thanks all who came down and got time on the track, weather was good

I must address the noise test issue, as there is something not quite right at Brands Hatch.

my 993 with modified exhaust, that runs 101db +


1st up their 3/4 calculation, which was based 6700 max revs which he wanted 5250 rpm, which came out at 104db+ failed then after questioning the maths he then asked for 5000rpm

noise test = 103.7 on the right and 102.2 on the left
that was a complete surprise

I then attempt a modification, which brings it down to 100.1db, success and I'm on track except the mod fails after a few laps, although I haven't tripped any of the drive by noise meters at any time at this point.

So I'm off track and he's saying the car will fail, then I ask him to retest it to get a reference so I can work on a better fix but then it comes up at 101.5db and I've passed after doing nothing and a difference of 30 mins between noise tests.

:dont know:

there is actually a simple and safe mod that's we've found locally that reduces the noise by 1.5db for straight tip and round exhausts, which may need to be the must have 996/997/991/Cayman mod

:thumb:

although later on my day came to an end when my brake master cylinder failed, but that's another and more lucky story :eek:

Nice to meet you.
It was a good evening.
Still can't believe we've not crossed paths in 20 yrs of going to the Ring.
Did you get picked up and was it late?

They were already the at the start of the event but not related to this flap mod,

I was lucky my brake master cylinder failed coming into surteees and no where else....

Got picked up by the AA way 10 after having to haggle with ADAC to get my car towed all the way home, got in just before 12.

Great evening and great to meet more forum folk!

I have lots of dashcam footage which I'm trying to upload to YooChoob so I'll post some links when it's done...

You know you've been on track when you chuck in £50 of fuel when you leave and the range shows 77 miles! :floor:

Hi all
Thanks for a great evening even though I completed only approx 5 laps before oil started to leak heavily from the front end of the engine :roll: I got off track as quickly as possible!

Hoping I caught it in time and everything is ok, still had oil pressure and it dropped a moderate puddle whilst cooling down so the level and dipstick still showed above minimum 2hours later.

Marshall towed me past all the ford lot who duly took the piss :mrgreen:

Looking forward to another track session soon and hopefully see some of you at porsche fest

Hi all,

Thanks for organising, I came across it by accident on the MSV website. Unfortunatley they are burn marks and not on there before the night. So DB lowered but with paint damage for the efforts, so a bit of fixing to be done. My GT3 has never struggled to get through testing in 10 years and it came in at 103.5!!.

So rather than take a bath on the booking I managed to get the flaps from a workshop across the road from Brands as a temporary fix and it did drop by 2db.

In hindsight I should have thought about the heat being generated and where it was going. With a bit of heat wrap and shielding it could be a cheap option, but I'm looking into a bolt on exhaust extension as a more permenant solution to the DB problem.

Really enjoyed the night and look forward to the next one, just with a big old exhaust extension hanging off the back

Great to see so many people getting out on track. Its so much safer than driving quickly on the road.

Ive had enough of brands now, I live just down the road and avoid it due to their approach to noise.

On a bone stock 996 GT3 i get kicked off yet I am fine at the notoriously low level Bedford.
 
I see N RAP was there, Jackals old car. I've followed it for 8 billion miles around Europe (although it was mostly behind me.) 😄

Who is the very proud owner? You've got a special one there.
